Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576716, here are decompositions:

7 + 31576709 = 31576716
13 + 31576703 = 31576716
43 + 31576673 = 31576716
97 + 31576619 = 31576716
137 + 31576579 = 31576716
167 + 31576549 = 31576716
233 + 31576483 = 31576716
239 + 31576477 = 31576716

Showing the first eight; more decompositions exist.
